Answer: 
Thank you contacting MasterFlow ... Yes, Generally this elbow can be attached to both the flex duct and the metal pipe. Some additional manipulation of the pipe or elbow maybe needed. Please contact our Technical Services Group at 800-211-9612, M-F 8A-5P EDT for any additional help.

Rated 3.7 out of 5 by 3 reviewers.
Rated 1.0 out of 5.0 by you get what you pay for I purchased three of these to rerun a dryer vent, I went from a side by side to a stack W/D. Years ago I worked in HVAC doing installs and replacements. This is by far the worst 90 degree fitting I have used. The first one pulled apart simply adjusting it from the 90 degree position. December 6, 2011
Rated 5.0 out of 5.0 by HVAC duct work materials I ordered numerous items including the 4" 90 degree HAV sheet metal elbows. They arrived professionally packed in just a few days and installed easily in my dust collection system in my shop. May 28, 2006
Rated 5.0 out of 5.0 by Very Adjustable Not much to say, but is very adjustable. Good for 90 deg, or 45 deg offsets. November 24, 2011
